What did you do?
when running tests with go1.14.6 and go1.14.7 still seeing log output of tests going to the wrong test #39308
tmp.zip
attached program runs a bunch of tests and checks for any output that went to the wrong test. It is a little random sometimes does work. Not positive but it seems to only ever be a TestABC1 & TestABC2 (or vice versa) yet to see one where it ends up on a different subtest for the some one
What did you expect to see?
no output
What did you see instead?
docker build -t gotestissue . && docker run --rm gotestissue
